METAL CAB-WTNDOW FRAME.

Application led July 7, 1915. Serial No. 38,569.

To all 'whom t may concern Be it known that CHARLES H.- TURNER, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Metal Car-Window Frame, of which the following is a specification.

rThis invention relates to a metal window frame particularly designed for use in passenger cars. For such purposes, it is essential that the sash t snugly toexclude dust and dirt, that they slide readily and that they shall not rattle. t is also important that provision be made for inserting or removing the sash from the frame with a minimum expenditure of time and labor.

it is the general object of my invention to provide a metal window ,frame which successfully meets these requirements, said frame embodying improvements in construction and in the relations of parts by which increased efficiency in operation and -economy of manufacture may be obtained.

With this general object in view one feature of my invention relates tothe provision of a window post comprising a core 4member and a casing secured thereto, said casing being formed in two parts entirely of sheet material and having the peculiarv cross-section hereinafter described.

A further feature of my invention contemplates the provision of outwardly 1nv clined sash grooves in a window post casing and of correspondingly beveled sash stiles cooperating therewith. This feature, combined with the use of a laterally spring pressed stile on one side of the sash, provides a close fitting frame in which the sash is forced normally outwardly to engage abutments provided on the outside of the frame, sash.abutments upon the inner side being thereby rendered unnecessary.

Further features of my invention will be more fully described in the following specification and will be specifically set forth in the appended claims. y

A preferred form of my invention and a modification thereof are shown in the drawl ,through the upper sash and above the lower sash; Fig. 2 is a detail elevation of an upper corner of a sash; Fig. 3 is a detail ele- Specicaton of Letters Patent.

member 10 andextend beyond said member' y toward the inside ofthe car.

'Ehe inclosing casing for the window post is formed of two sheet metal parts 12 and 13. The part 12 has a general U-shaped section, the central portion thereof being secured to the core member 10 and the side portions or plates 11 thereof near their forward ends engaging the clips 11. At the point of engagement with the clips 11 the plates 14 are bent inwardly to form curtain grooves 15. ln addition to the grooves 15 the side plates 14 are each provided with parallel outwardly inclined sash grooves 20 and 21, separated by a narrow connecting flange 22. rllhe member 12 is also bent to form abutments 28 which form the outer guides for the upper sash. The part 13 of the post casing forms an inner cap having flanges 16 closely fitting outside of similar fianges 17 formed at the ends of the side plates 14. The cap 13 is secured to the clips 11 by screws 18 and is of such outline as to y rovide convenient recesses 19, which may )e used as conduits for electric wires.

Both the upper and lower sash are formed with the usual top rails 21 and bottoni rails 25 and with side stiles 26 and 2T having beveled outer edgeswhich engage the tapered grooves 20 or 21. On one side of each sash the stile 26 is of solid construction, and is shown in the drawings as formed of wood and having a metal sheathing 2G" applied thereto. The opposite stile 2T of each sash is of compound construction and is preferably formed entirely of metal. This stile comprises an inner or glass-engaging member 28 and an outer or post-engaging member 29, the latter `member being beveled on its outer face for engagement in the grooves 20 or 21. The outer member 29 is formed to slide over the member 28 with a telescoping action and is Provided with a cap at each end .to prevent relative longitudinal displacement of the members 28 and 29. Said members are normally forced apart by anumber of flat springs 31 secured to bosses 32 upon the'inside of the member 29, said springs with theirl free ends engaging the inner member 28. At their'upper and lower ends the inner members 28 are provided with flanges 28a (Fig.l 2) which are secured by screws 28b to the-upper and lower rails 24: and 25.- The ends of the rails are recessed as shown at 24a to permit free inward movement of U-shaped lugs 33 secured to theinner surface of the outer or movable stile members 29. Screws 34 eX- tend through openings 35. in the lugs 33 into the ends of the rails `24 and 25. rlhe heads of the screws 34 limit outward motion of the stile members 29`while yielding inward motion is unrestricted. With this! construction each sash may be readilyinserted wlthin the frame by placing its yielding stile member 29 against one of the inclined sash grooves 20 or 21 and by thereafter compressing the springs 31 until the corresponding solid stile 26 can be `slipped into the opposite groove. As the sash is released, the springs 31 will force outwardly the movable stile member 29 thereby. caus-jv ing the sash to closely engage its casing. The engagement of the sash with the inclined grooves'20 or 21 will also automatically move the sash as a whole outwardly until it engages either the straightconnecting Hanges 22 or .the outer abutments 23, the upper sash usually engaging the 'abut- `yments.

A sash lock .36 of any usual form may be provided for retaining the sash in desired vertical position.

ln the modified construction shown in Fig. '4 the core member 100 is formed of sheet metal and is provided with spacing blocks 101 at the point where the* clips 110 -are secured thereto. The core memberis also extended across the post, so that thev screw 18 which secures the cap engages not' only they clipA 110` but also the core member 100. With these exceptions the construction is similar to that already described.

vcomprising a core member ,having a T- shaped section, a plurality of spacing clips l secured to the web of said core member and having vertical space between them, a casing memberhaving a substantially U-shaped section secured along its center to the flat outer face of said core member and engaging said clipsnear the ends of its side portions, and a cap detachably secured to and supported by said clips and forming the inside casing of said'post, said cap having -side flanges embracing and covering the ends of the side portions of said U-shaped casing member and being movable to expose the entire interior of the U-shaped section,

said interior being open from front to bacl between the clips. v

2. A -post for a metal car windowjframe l comprising a core member having portions 'extending at right angles to each other and having spacing clips spaced apart vertically secured to the center` portion thereof, a sheet metal casing member having a substantially U-shaped section and having its center portion permanently secured to the outer face of said core member and its side portions engaging the sides of said separated clips, and a cover plate detachably secured to said clips to form the inner facer-) said post, embracing the free ends of said side portions of said casing member and adapted when detached to expose the entire interior of the U-shaped section so as to leave the interior vopen from front to back between the clips, said side portions being provided with outwardly-inclined sash-holding grooves.

A In testimonywhereof 'I have hereunto set my hand.
